Okay I didn't forget, just got caught up in the business of life. The little experiment of holding an object up to each eye and staring through the center for awhile, then noting which direction your eyes tend to move, shows you if you're right or left-brained. If your eyes moved to the left, you're right-brained (so "they" say) and if to the right, you're left-brained. There's some basic data for this, as many left-handed people looked to the right - meaning their left frontal lobe was more active. The brain is so complex yet perfectly contained, isn't it?
It's normal to imagine our brain starts at the top of our head and ends at the bottom, but it's not so at all. Your brain matter is directly behind your eyes, and ends around the middle of your skull. Something like this:
